PFC Power Supplies
(OP)
With today's advent of power factor correcting power supplies, I wondered how many of you out there(that have raised floors and UPS backup), have seen increasing leading power factor? I have heard of static UPS's dumping the critical load once the power factor starts to go leading.

fundamental power factor: cosphi
and true power factor: lambda
Terms as leading and lagging can only be applied if you are talking about fundamental power factor.
In the case of power computer powers supplies discussions on fundamental power factor are not worth the time spent because low power factor is mainly caused by harmonics.
